Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 108,737,767, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 108,737,767 | |
| -1 | -108,737,767 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 108,737,767.
Example:
1 x 108,737,767 = 108,737,767
and
-1 x -108,737,767 = 108,737,767
Notice both answers equal 108,737,767
With that explanation out of the way, let's continue. Next, we take the number 108,737,767 and divide it by 2:
108,737,767 ÷ 2 = 54,368,883.5
If the quotient is a whole number, then 2 and 54,368,883.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 108,737,767 | |
| -1 | -108,737,767 |
Now, we try dividing 108,737,767 by 3:
108,737,767 ÷ 3 = 36,245,922.3333
If the quotient is a whole number, then 3 and 36,245,922.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 108,737,767 | |
| -1 | -108,737,767 |
Let's try dividing by 4:
108,737,767 ÷ 4 = 27,184,441.75
If the quotient is a whole number, then 4 and 27,184,441.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 108,737,767 | |
| -1 | 108,737,767 |
If you did it right, you will end up with this table:
| 1 | 23 | 59 | 227 | 353 | 1,357 | 5,221 | 8,119 | 13,393 | 20,827 | 80,131 | 308,039 | 479,021 | 1,843,013 | 4,727,729 | 108,737,767 |
| -1 | -23 | -59 | -227 | -353 | -1,357 | -5,221 | -8,119 | -13,393 | -20,827 | -80,131 | -308,039 | -479,021 | -1,843,013 | -4,727,729 | -108,737,767 |
